How is Hamartoma Diagnosed

The incidence of hamartoma is getting higher and higher. Many people suffer from this disease, but they don't know how to diagnose it. Many people miss the best treatment time because they don't get a timely diagnosis. I have collected a lot of information. Now let's learn about how hamartoma is diagnosed!

The diagnosis of hamartoma can be based on the following aspects:

1. X-ray examination

X-rays show uniform and dense shadows, or uneven shadows, and calcification. The calcification shows a popcorn-like pattern, and the density of the peripheral part is relatively low, which may be adipose tissue. The popcorn sign is a characteristic manifestation of pulmonary hamartoma, but it is rare and not unique to pulmonary hamartoma. Chest X-rays can detect the presence, size, and presence of satellite lesions of SPN. Obvious popcorn-like calcification is found, which facilitates dynamic observation of lesions. Fibrous hamartomas have no calcification, and fat density is difficult to judge on traditional X-rays and is often misdiagnosed.

2. CT examination

① The edge of the lesion is smooth, mostly round or quasi-round, without burr sign, but may have lobulation sign.

②The lesions are mostly smaller than 5 cm.

③The masses are mostly soft tissue density masses, which often contain fat density areas, which are their typical CT manifestations.

④ Calcification in the lesion is spotty or patchy, and the typical calcification is popcorn-like.

⑤ Most of the lumps are located in the lungs, a few are close to the hilum of the lung, and some are located in the tracheal cavity. There are no enlarged lymph nodes in the hilum of the lung and the mediastinum.

⑥ After enhancement, the mass showed no enhancement or only slight enhancement.

3. Imaging examination

(1) Ultrasound examination is quite characteristic. The fat and blood vessels in the tumor show evenly distributed dense high-echo areas, while the muscle and hemorrhage parts show low-echo areas.

(2) X-ray abdominal films show unclear renal contours, disappearance of the psoas muscle shadow, and calcification in the renal area. Urinary tract angiography shows that the mass compresses the renal pelvis and calyces, causing them to deform, lengthen, or shorten, but without any invasion.

(3) CT is the main method for diagnosing hamartoma. It is a mass with uneven density and high fat content, and the CT value is -40 to -90 Hu.

(4) MRI In recent years, MRI examination has also played an increasingly important role in the diagnosis of hamartoma.

The above is the diagnosis method of hamartoma. Therefore, if you feel unwell, you should go to the hospital for examination and treatment regularly in time, and do not delay the best treatment time.
